Lawyers for one of the men accused of murdering a mother of six claim that the real killer is another man who's currently wanted in that case, as well as a second homicide.

Dorian Peebles, 22, appeared in Municipal Court on Friday for his preliminary hearing. Pittsburgh police believe he and James Lawrence, 21, killed Tiona Jackson, 28, and injured a man walking with Jackson after leaving Red's Ringside Cafe in Beltzhoover in February.

Investigators believe Peebles, Lawrence and another man were involved in a verbal argument in the bar. At Friday's hearing, a man who was with the group testified that as they were driving away from the bar, Lawrence and Peebles opened the door, got out and opened fire on Jackson and the other man, who survived.

Peebles' defense attorney, Nicole Nino, claims that her client didn't fire a single shot and that Lawrence is the true shooter.

"Unfortunately, you are judged by the company you keep," Nino said. "But we will prove beyond a reasonable doubt that you are not who you hang out with on a Friday night."

Nino pointed out that Lawrence is also wanted for a homicide that happened in Sheraden about one month after Jackson's killing. In that case, police allege that Lawrence and Michael Lyons shot Steven Lee, Jr. after pulling him from a party bus.

Lawrence has not been caught.

Peebles is facing charges that include homicide and aggravated assault. A judge on Friday held all charges for trial and sent Peebles back to the Allegheny County Jail to await trial.
